    If your blower is noisy and not from pine needles or leaves or debris sucked in from the glove box like papers or straw wrappers, it may simply be the motor going out. Next time it doesn't work, give the blower motor a solid smack while it is turned on. Most of the time this will make it start to come on as soon as you smack it. Same thing works with window motors, fuel pumps, etc. good trick to make it work for now until you can replace it
    Appreciate this feedback -- it follows what I had been thinking, including the smack this last go round (though it was a gentle one ;-) And, once I get the time, I'll put to use the tips you offered about accessing the connector!

    That's what I hoped!

    Super -- I had the service manual but not some of the supplements or the link to the service bulletins -- thank you!

    Then you know if power is getting to the motor.
    Good call - there was +12V going to the motor (after a "doh" moment when I realized I had to have the fan switch on ;-)

    Sound like you need a new fan motor.

    But keep in mind the fan switch and watch for the blinking AC light.
    You'll know what to do if (or probably when) that happens.

    I'd suggest getting the motor with the blower wheel attached. (it's the cheapest one anyway)

    I removed my blower motor about 5 years ago and took it apart to clean and oil it.
    There is a clip on the end of the shaft that holds the blower wheel on and it really hard to get off.

    I ended up breaking the plastic wheel a bit but luckily managed to get it back together.





    There is a big piece of felt at the end of the shaft that supplies oil to the bushing and it was dry so I filled it up.
